Original Abstract

In this paper, a new first-order all-pass filter based on single differential-input buffered and transconductance amplifier (DBTA) as an active element, single capacitor, and single resistor is presented. The proposed circuit works in both voltage- and transadmittance-mode simultaneously and is fully cascadable due to high-impendance voltage input and low/high output-impedance of voltage/current outputs, respectively. The behavior of the filter is verified by SPICE simulations using commercially available ICs OPA860 by Texas Instruments to confirm the theoretical analyze.
